> Calling JarFinder.getJar() throws an exception if user has a
> "META-INF/MANIFEST.MF" in the same directory of the .class specified.
> Jarfinder.getJar() call createJar() that always create a new Manifest and
> then add all the files contained in the .class directory.
> To reproduce the problem in a simple way you can create a SimpleClass.java in
> the same directory create a META-INF/MANIFEST.MF and then call
> JarFinder.getJar(SimpleClass.class)
> {code}
